Summary

Carotid stenosis usually results from the accumulation of atherosclerotic plaque in the carotid artery wall and is an important risk factor for ischemic cerebral vascular accident (CVA). This study describes the importance of diagnostic imaging exams used in dentistry for the early identification of atheroma plaques in the extracranial and intracranial internal carotid artery. A male patient was referred to a radiology clinic to perform panoramic radiography (PR) and a cone beam computed tomography (CBCT) to develop treatment plan options. In the PR and CBCT a radiopaque image, suggestive of atheroma in the extracranial internal carotid artery, was observed on the right side. The diagnosis was confirmed by color DOPPLER ultrasonography. In the CBCT, the presence of calcifications in the intracranial internal carotid artery was also observed. Diagnostic imaging exams used in dentistry allow the identification of asymptomatic individuals, facilitating early intervention and consequent reduction in the risk of ischemic CVA.

KEY WORDS: cone beam computed tomography, panoramic radiography, color doppler ultrasonography, atherosclerosis.
